In depth
Agent sandboxing means running an agent's commands inside a boundary enforced by the operating system or a VM. A bad command or a prompt injection can then only reach the files, processes, and network hosts you allowed. Claude Code's built-in Bash sandbox, for example, uses Seatbelt on macOS and bubblewrap on Linux and WSL2, limits writes to the working directory and temp space, and sends network traffic through a proxy that checks a domain allowlist. Because the OS enforces those limits, sandboxed commands can run without per-command approval, but only what the sandbox wraps is covered: in Claude Code, the file tools, MCP servers, and hooks run outside it.
